Abstract

The invention discloses a novel special ceramic material preparing method. The method comprises the steps of mixing red clay, albite, wollastonite, nanoscale aluminium oxide and niobium pentoxide, placing the mixture in a ball mill to be milled, conducting screening with a 230-mesh screen, placing auxiliaries and boron nitride into the ball mill for ball milling for 18.5 h, adding potassium hydroxide, continuing to conduct ball milling for 2.5 h, conducting washing till PH value becomes 7.6, and conducting filtration to obtain powder. By optimizing existing preparing methods and selecting proper technological parameters, the prepared novel special ceramic material has a uniform and dense interior structure, high strength, high corrosion resistance and oxidation resistance, high tenacity and hardness, high infrared reflectivity on the premise that high temperature resistance is realized, and excellent heat insulation performance.

Description

Technical field [0001] The invention relates to the field of ceramic material preparation, in particular to a method for preparing a novel special ceramic material. Background technique [0002] At present, ceramic materials are developing rapidly and are widely used in various fields, such as metal materials, insulators, pipes, etc., but existing ceramics have the following problems: such as too much brittleness, low strength, low heat resistance, etc., and processing methods The cost is high and the product benefit is low. Therefore, it is necessary to study ceramic materials with good wear resistance, high hardness, good toughness, vibration resistance, heat resistance, corrosion resistance and other excellent properties. Summary of the invention [0003] The purpose of the present invention is to provide a method for preparing a new type of special ceramic material in view of the above-mentioned problems. By optimizing the existing preparation method and selecting appropriate ...
